Abstract
A rotary compressor includes a support member for supporting a revolution piston while preventing rotary movement thereof with respect to its axis, and at least two sliding blades provided in the revolution piston. Both blades are biased against a surrounding cylinder by a one-piece spring. The maximum volume of the chamber is larger than the conventional chamber due to reciprocal movement of the slidable blades. The blades are positioned or rest at almost the same position in the radial direction of the revolution piston. Therefore, any inertia which effects the spring due to the sliding blades is very small. Thus, the sliding blades press the cylinder with almost constant force which is predetermined by the spring, even if the revolution piston changes the rotational speed thereof.
